| Technique | Description | |-----------|-------------| | Low crawl | Body flat on ground, using elbows and knees/toes to inch forward. Best under enemy fire or open terrain. | | High crawl | Belly off ground, supporting on forearms and knees. Faster but slightly higher profile. | | Hand-and-knees | Used in thicker vegetation or when noise is secondary to speed. | | Scoot & pause | Move 3–5 seconds, stop, listen, scan (using peripheral vision). |
FU-10 is often used as a shorthand in military, law enforcement, or serious airsoft training environments to refer to a specific land navigation or movement technique under low-light conditions. “Night crawling” describes the method of moving quietly, slowly, and close to the ground to avoid detection, maintain cover, and navigate safely after dark. fu 10 night crawling
While not a universal standard code, in many field manuals or unit-level training (e.g., referencing FMs like 21-76 or similar), a “10” may indicate a movement category or step. Here, we’ll treat FU-10 Night Crawling as the disciplined practice of low-visibility ground movement. Standing up breaks the horizon line
| Enemy | Behaviour | Counter‑Strategy |

| Standard Animatronics (A‑1, B‑2, C‑3) | Follow the same patterns as nights 1‑9. | Use the same tactics you already know: door‑close on audio cue, flash lights briefly. |
| Crawlers | • Spawn in Vent‑B and Storage‑C every 30–45 seconds.
• Move at 1.8 × normal speed.
• Can travel on walls/ceilings, becoming invisible after 2 m. | 1. Listen – “scrape” sound = crawler on floor, “drip” sound = crawler on ceiling.
2. Light‑Flash – When you see a silhouette, flash the light (double‑tap L). This re‑illuminates the Crawler for 2 seconds.
3. Sweep – Activate Infra‑Red Sweep right after the “drip” cue; the sweep will outline the Crawler on the ceiling for a short time.
4. Door‑Close – If a Crawler reaches the doorway, close that door immediately; the door will hold it for the remainder of the night. |
| Hybrid “Shifter” (appears after 3 minutes) | Switches between floor and ceiling every 8 seconds. | Keep the Infra‑Red Sweep active for a full 8‑second cycle the moment you hear the first “shifter” cue (a high‑pitched whine). The sweep will lock its position for the duration of the cycle, giving you a safe window to clear it with the lights. | referencing FMs like 21-76 or similar)
Standing up breaks the horizon line. Even in pitch black, a standing player against a slightly less dark sky is a killable target. Crawling keeps your profile below grass lines, rock edges, and debris. You blend into the terrain’s shadow baseline.
Ironically, the best tool for night crawling is a Flashlight—not to see, but to bait.
Night crawling is inherently riskier than daytime movement. Always follow these rules:
